- Editor's Notes
- [TAE marg: "Tate Translate this can't read E"; typed transcription follows.] "Many contrivances have been put forth to cause the sound of a voice transmitted to the telephone to be freed from outside disturbing influences and to cause it to be more distinctly enunciated through it. None of those, so far as I have knowledge, seek to modify the original sound or to alter its pitch. ### Now some voices are better distinguished through the telephone than others-that of a woman or lad for instance. ### Would it be possible to invent an apparatus to be attached to a telephone, which would produce a "telephone voice?" I mean by this, a contrivance that will so alter and change the pitch of the voice uttered into it, by means of reeds or otherwise, as to make it most fit for telephonic communication. For instance, change a deep bass to a shrill, clear treble. ### I have not studed acoustics and for aught I know, this communications might well have been dated for days back." TAE marg: "I think it possible but unpractiacable. There is no such thing as a telephone voice in a good transmitter. The present apparatus used for telephoning is an amateurs device and is not a good transmitter E"]
